How do you determine the number of partitions? For example, I have 16 workers, and the number of cores and the worker memory set in spark-env.sh are:
CORE = 8 MEMORY = 16g The .csv data I have is about 500MB, but I am eventually going to use a file that is about 15GB. Is the MEMORY variable in spark-env.sh different from spark.executor.memory that you mentioned? If they're different, how do I set spark.executor.memory? -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/ERROR-TaskSchedulerImpl-Lost-an-executor-tp4566p4621.html Sent from the Apache Spark User List mailing list archive at Nabble.com.
